Katha(s) for wearing thai amulets

Just asking - anyone know sort of like a general katha(s) to recite before and after wearing the thai amulets? Is there like some katha(s) to enhance or awake the amulets before wearing it? Thanks!

Generally, most of the mainstream amulets can use:

namo tassa bhagavato arahato sammāsambuddhassa (x3)

General mainstream.

Namo Tassa Bhagavato Arahato Sammma Sambuddhassa x 03

Then : Kata for Chanting to Amulets (Kata Aaratanaa Pra Krueang)
Puttang Aaraatanaanang, Tammang Aaraatanaanang, Sangkang Aaraatanaanang.
Puttang Prasittimae, Tammang Prasittimae, Sangkang Prasittimae.

Chant this Kata 3 times whenever you are about to wear or take off.
The Kata calls upon the power of the Buddha, Dhamma and Sangha to be with you and protect and Guide you.
